Stockfish itself does not support EGTB. You were probably
playing at a very fast clock speed, maybe a 1 minute vs. 1 minute
game. That is why if you give it a bit longer, it will find the
mate. Many GUIs allow you to specify the EGTB path so that the GUI
will take over if the position is matched (e.g. Fritz).

That Stockfish had 3 minutes left and could not find such a
simple mate is certainly strange. In Fritz, if you go to Options,
there's a you specify the table base path for the GUI and the
engines separately. Also, Houdini uses Gaviota table bases,
correct? I believe for Fritz you need Nalimov table bases. Finally,
can you please reattach the game as a PGN file? "cbtourn" is a
proprietary ChessBase format that I can't open.
I'm sorry, but is there a there a way that I can save it to that
format? It was played within DF12 GUI.
And, I do have the EGTB set up in options. Yes, Houdini uses it and
it shows at the end of the game.
I do appreciate your help. And just to let you know, Stockfish has
been winning against Houdini, even as black. And I've checked the
settings to make sure they are even and correct - and they are. I
really figured Houdini 1.5a to do better from all I've read.
Please let me know what you think and if you need anything
Where can I get the Nalimov bases? Do they also have a 6 men?
BTW, I've also started using the GUI Arena and am starting to
really like it.
Once again thank you for your time :)
Thanks. Yeah, I don't understand why it didn't get the mate. You
have any thoughts? (Exact time left was 2 mins 55 secs.)
So, SF can use Gaviota if I play it under Arena?
Again thanks, I will get out of your hair now. You've been
It doesn't have nothing to do with tablebases. I have tried to
reproduce the bug, but when replaying the game in FritzGUI was
impossible to reproduce the moves because SF was always suggested the
I'd guess is due to interaction between draw score due to 50 moves
rule and hash tables saved scores.....some more research is needed.
